We never really know what's around the corner when we're filming - what turn a story will take, what a character will do or say to surprise us, how the events in the world will impact our story.

I've always been interested in how people think, how they react to challenges in their lives - what makes people tick. I've also always been passionate about social issues and causes, and I wanted to make films that addressed important issues in very human terms.

I turn down invitations to events where I know there will be politicians.

I never work from an outline, and often I don't know how the story will end.

We are like chameleons, we take our hue and the color of our moral character, from those who are around us.

Most of my films have been documentaries, but I'm also very interested in narrative filmmaking.
